EYEGLASSES.

SPECIFICATION forming part of Letters Patent No. 765,566, dated July 19, 1904.

Application filed February 5, 1904. Serial No. 192,132. (No model.)

T0 a/ZZ 'wit/)Tw it Ntrty concern:

Beit known that I, VVILLARD W. Dow, a citizen of the United States, residing in Malden, in the county of Middlesex and State of Massachusetts, have invented an Improvement in Eyeglasses, of which the following description, in connection with the accompanying drawings, lis a specification, like letters on the drawings representing like parts.

This invention relates to frameless or'rimless eyeglasses, .and has for its object to provide the same with nose guards or pieces which are free to move, so as to adapt themselves to the nose of the wearer, whereby the glasses may be held firmly on the nose Without danger of injuring the same.

In accord ance with this invention the clasps or settings are secured to the lenses above the longitudinal axes of the same and are provided with depending or downwardly-extended arms, from which extend laterally studs or pins upon which the nose guards or pieces are mounted to turn, so as to conform to the shape of the nose of the wearer. The nose guards or pieces are held in engagement with the nose with a yielding pressure created by the bridge-spring connecting the clasps or settings.

Injury to the metal parts of the eyeglasses by frequent putting on and taking off of the glasses is avoided by securing the settings or clasps to the lenses above the longitudinal axes of the same a sufcient distance to bring the pivots for the nose-guards substantially in line with said longitudinal axes.

These and other features of this invention will be pointed out in the claim at the end of this specification.

Figure 1 is an elevation of a pair of eyeglasses embodying this invention; Fig. 2, an enlarged section on the line 2 2, Fig. l, looking toward the left; and Fig. 3, a detail in perspective to be referred to.

Referring to the drawings, the lenses a have secured to them the settings or clasps which are fastened to said lenses by screws c, extended through the Settings and through suitable holes made in the lenses above the longitudinal axes of the same.

The clasps or settings in accordance with this invention are provided with downwardlyextended arms CZ, having laterally-extended studs or pins e, constituting the pivots for the nose guards or pieces f, which maybe made of celluloid, metal, or other suitable material and which may be provided with serrations g or left smooth, as desired. The nose-guards f turn freely on the studs or pins e and may be retained thereon by washers L, secured on said pins or studs by upsetting the ends of the latter or in any other suitable manner. The armsd are preferably made of su flicient length, and the pins or studs e are so located on said arms as to bring the said studs or pins substantially in line with the longitudinal axes of said lenses. K

The settings or clasps are connected by a yielding bridge, which may be of any usual or suitable construction and in the present instance is shown as consisting of arms z' j, eX- tended upwardly from the settings or clasps and provided with substantially fiat horizontal portions c m, which slide on each other and are acted upon by a helical spring a, en-

circling one of said horizontal members between the end pieces or heads 0 p onv said members.

From an inspection of the drawings it will be seen that the pivoted nose-guards are free .to turn, so as to conform to the shape of the nose, and thereby obtain a broad and firm bearing or engagement therewith without eX- erting severe and oftentimes painful pressure on the nose.

It is further to be observed that the pivoted guard is attached to a setting or clasp which is small and requires but a single hole to be made in the lens for attachment thereto.

By connecting the settings or clasps to the lenses above the longitudinal axes thereof the pivots for the nose-guards are brought substantially in line with saidaXes andthe length of the upwardly-extended arms jof the bridge is shortened, so that they are less liable to be bent, distorted, or broken when the lenses are separated in the act of putting on or taking off the glasses.

I may prefer to employ the spring-bridge herein shown; but I do not desire to limit my invention in this respect, as the invention is IOO ' equally applicable to rimless eyeglasses in with the longitudinal axis of said lens, anoseguard loosely mounted on eacli stud or pin, and a bridge connecting said settings or clasps, substantially as described.

In testimony whereof I have signed my name to this specilication in the presence of two subscribing Witnesses.

WILLARD W. DOW.
